I Save the Vampires from the Start

In this world, strength reigns supreme. Fifty million years ago, the God of Darkness laid a curse, and the Yao clan came to believe that every unborn child was the bane of their people, destined to bring about their extinction. To fulfill their mission of saving the Blood Clan and the Yao clan, the God of Wind and the God of Thunder sent Melo down to the mortal realm to undergo tribulations. After becoming the Blood God, Melo would return to save the souls of both clans. Only when the Blood God descended upon the Blood Clan again could peace return to the world.
